# Questionnaire data

A number of motor ability and health related factors were collected using questionnaires. 

Questionnaires were distributed to and filled in by participants either using paper versions, or digitally using [REDcap](https://www.project-redcap.org/). Swedish versions of the questionnaires were used, and answers are recorded in Swedish as well.

Data collected includes:

- Handedness using the Edinburgh Handedness Inventory (EIH)
- Anxiety and depression via the Hospital Anxiety and Depression Scale (HADS)
- Walking ability via WALK-12G - for OA and PD
- Disability using WHO Disability Assessment Schedule (WHODAS) - for OA and PD
- Motor function and disease severity via MDS-UPDRS 1b/2 - for PD
